There are a lot of things that are equivalent to 16/81.

16/81 = 0.197530864

Or we can keep multiplying 2 to the numerator and denominator:

16/81 = 32/162 = 64/324 = 128/648

I need help with number 6

antiseptic1488 [7]

A. 63.23
That is the answer because you would add all the times together (57.38+60.92+58.47=176.77) then subtract that from 4 minutes (240 seconds) (240-176.77=63.23)

Jason and Jeremy work together at a juggling-ball factory. Jason lives 25 miles away from the factory and drives at 60 miles per

postnew [5]

Jason arrives at the factory first

It takes 5 minutes until the other person arrives

Solution:

The time taken is given by formula:

$Time\ taken = \frac{distance}{speed}$

Jason lives 25 miles away from the factory and drives at 60 miles per hour

Therefore, time taken by Jason is:

$Time\ taken = \frac{25}{60}\ hour$

Convert to minutes

1 hour = 60 minutes

Therefore,

$Time\ taken = \frac{25}{60} \times 60\ minutes = 25\ minutes$

Jeremy lives 35 miles away from the factory and drives at 70 miles per hour

Therefore time taken by Jeremy is:

$Time\ taken = \frac{35}{70}\ hour\\\\Time\ taken = \frac{35}{70} \times 60\ minutes\\\\Time\ taken = 30\ minutes$

They leave their houses at the same time

25 minutes < 30 minutes

Thus Jason arrives first

Jason arrives to the factory in 25 minutes

Jeremy arrives to the factory in 30 minutes

⇒ 30 - 25 = 5 minutes

Jeremy arrives after Jason by 5 minutes

It takes 5 minutes until the other person arrives

Answer:

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Distributive Property

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Algebra I

Terms/Coefficients
Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

2x - y = 11

x + 3y = -5

Step 2: Rewrite Systems

2x - y = 11

[Subtraction Property of Equality] Subtract 2x on both sides: -y = 11 - 2x
[Division Property of Equality] Divide -1 on both sides: y = 2x - 11

Step 3: Redefine Systems

y = 2x - 11

x + 3y = -5

Step 2: Solve for x

Substitution

Substitute in y [2nd Equation]: x + 3(2x - 11) = -5
[Distributive Property] Distribute 3: x + 6x - 33 = -5
Combine like terms: 7x - 33 = -5
[Addition Property of Equality] Add 33 on both sides: 7x = 28
[Division Property of Equality] Divide 7 on both sides: x = 4
